Isocyanic acid is a chemical compound with the structural formula HNCO, which is often written as H−N=C=O. It is a colourless, volatile and poisonous gas, condensing at 23.5 °C. It is the predominant tautomer and an isomer of cyanic acid (aka. cyanol) ( H−O−C≡N ), and the monomer of cyanuric acid .
Thiocyanic acid is a chemical compound with the formula H S C N and structure H−S−C≡N, which exists as a tautomer with isothiocyanic acid (H−N=C=S). [8] The isothiocyanic acid tautomer tends to dominate with the compound being about 95% isothiocyanic acid in the vapor phase. [9] Tautomerism between thiocyanic acid (left) and ...
The cyanate ion is an anion with the chemical formula OCN −. It is a resonance of three forms: [O − −C≡N] (61%) ↔ [O=C=N − ] (30%) ↔ [O + ≡C−N 2− ] (4%). Cyanate is the derived anion of isocyanic acid , H−N=C=O, and its lesser tautomer cyanic acid (a.k.a. cyanol), H−O−C≡N.
Hydrogen cyanide (formerly known as prussic acid) is a chemical compound with the formula HCN and structural formula H−C≡N.It is a highly toxic and flammable liquid that boils slightly above room temperature, at 25.6 °C (78.1 °F).

The chemical that actually has that structure, isofulminic acid (a tautomer of the actual fulminic acid structure) was eventually detected in 1988. [ 3 ] The structure of the molecule has been determined by microwave spectroscopy with the following bond-lengths - C-H: 1.027(1) Å , C-N: 1.161(15) Å , N-O: 1.207(15) Å .
Thiocyanate [6] is known to be an important part in the biosynthesis of hypothiocyanite by a lactoperoxidase. [7] [8] [9] Thus the complete absence of thiocyanate or reduced thiocyanate [10] in the human body, (e.g., cystic fibrosis) is damaging to the human host defense system.
